Triple immunofluorescence for the axonal tracer FB (blue), TRPV1 (red), and CGRP (green) in sections of mouse lumbar DRG (tracer injection sites and DRG segments are indicated on the bottom). Intraarticular injections of FB label afferent neurons that innervate joints, many of which co-immunostain for TRPV1 and CGRP (solid arrows; examples of articular afferents that immunostain for either TRPV1 or CGRP alone are pointed to with open arrows). Scale bars = 50 µm.
